IMPROVED MODE OF OILING CAR-AXLE BEARINGS.

Specification forming part of Letters Patent No. 39,017, dated June 23, 1863.

To all whom it may concern:

Be it known that I, B. ll). STEVENS, formerly of Burlington, in the county of Chittenden, in the State of Vermont, but now of Lawrence, in the county of Essex and State of Massachusetts, have invented certain new and usefulImprovementsin Ciling CarvAxles or Journals; and-I do hereby declare that the following is a full, clear, and exact. description ot` the same, reference being had to the accompanying drawings, forminga part of this specitication, and in which- Figure l represents a plan or top view ot' my improved device. Fig. 2 represents a section on line A B, Fig. 1, and Fig. 3 represents a section of the device when in position and on a car ready for use.

In the drawings, J represents the hangeriron and box, which keeps the axle F and its bearing C in proper position. These parts are made in the usual form and need no further description.

I is the usual rubber spring. B is alsmall wheel or roll which turns on a spindle or journal, A, whose ends are flattened or cut away to lit into grooves or recesses cut or cast in the ends of the inclined top of C. The center or" C is cut or cored out in casting so as to permit the roll B to pass down through it, as indicated in the drawings. Each corner a of the part C is cast thick enough to permit of a hole being drilled therein to receive a coil spring, as indicated in dotted lines, Fig. 3.

'.lhe operation is as follows: The part C is cast so as to t into the space in the hanger-iron or box J, below the axle F, and

when so placed for use is supported by four coiled springs, D, which keep the roll B up against the under side of the car axle F,as clearly shown in Fig. 3. When the parts are all properly adjusted, oil or otherflubricating compound is turned in until it rises so as to cover the lower part ot' the rollB, which,

when the car is in motion is caused to revolve by the movement ofthe axle F, thus carrying up the oil and rolling it upon the axle F, which in turn carries it up against and under its bearing G, whereby the oil is worked oil' laterally so as to keep the entire bearing well oiled and lubricated. In case the oil is carried up too fast it will simply drop down upon the inclined top of C, from whence it runs down its inclines through the opening in its center into the space below the roll B, to be again operated upon. In case the hangerircn or box J is not oil-tight, a. separate oilbox, E, can be placed in position to hold the oil and the oiling device A, B, and C.

My device is very simple, can be constructed at small cost, and applied to any ofthe cars in use. It has been tested and the saving of oil is very great, while its simplicity is the subject of favorable recommendation.

Having described my improvement, what I claim as my invention, and desire to secure by Letters Patent, is-

The peculiar car-axle oiling device A, B, and C. applied as and for the purposes stated. 1
